In transgenic mice, DNA is introduced into the germ line and that gene is stably inherited to the offspring of the mice. Transgenic mice have been

The oncogenic virus-induced tumors have provided the most direct evidence for these points; viral gene products elicit specific immune resp

Once operational definitions have been made, investigators can and should pursue questions of molecular mechanisms to explain phenotypic changes that occur during promotion and progression. This paper deals with the identification and characterization of molecular ma

Interval 1: Grandma Baré’s Diaryelated concepts of promotion and progression describe an essential feature of carcinogenesis, the gradual change from a normal cell to a tumor composed of proliferating, invading, metastasizing cells. Promotion is the gradual conversion of undetectable initiated cells to tumors without the continuin
